My experience of grinding in another world

Chapter 745 Mutation
The interior space of the keelboat is generally elongated and elliptical.

The ceiling is tens of meters high, and it is inlaid with many luminous pearls, illuminating the entire space.

A crystal-clear, shallow river meanders through the area, with hundreds of exquisite waterside pavilions scattered along its banks.

At the source of the river, there is a square pool made of stone slabs. In the center is a turtle statue that rises above the water, and droplets of water fall from the edge of the millstone-sized turtle shell, like a water curtain.

Chen Mu stood by the pool, leaning against the gray stone railing, staring at the turtle statue with great interest.

A little magic power was poured into the dragon bone boat, and the turtle's nostrils immediately spewed out a mist that gathered into a ball in mid-air.

The light and shadow shifted within the cloud, revealing a dim underground water vein landscape.

This cloud of smoke is a magical feature inherent to the keelboat, called the Luo Yan Mirror. It acts as the eyes of the keelboat, allowing it to detect the surrounding area.

"Duyuan, continue diving down along the underground water veins of Tangshan Hot Spring. In a few days, we will reach the Earth Fire Lake."

"That place is where magma and fire converge, and it can connect to the Heavenly River Cave's Fire Eye."

"From there, we can enter the Heavenly River Cave."

Heavenly River Cave Heaven...

Chen Mu raised an eyebrow slightly.

He recalled his experience of moving from Yunzhou to Haizhou, when they had also entered a grotto-heaven called the Heavenly River Dharma Realm.

"Tianhe Cave Heaven was created by the seventh generation master of the Chen-character Tianhe Water Mansion."

"Unfortunately, the descendants were unworthy, and all three Heavenly River Water Palaces in Yizhou were destroyed and disappeared for many years, so the Heavenly River Grotto became ownerless."

"Sixty-two years ago, my ancestor Tang family accidentally discovered the entrance to the Fire Eye in the Earth's core lake, and thus entered the Heavenly River Cave Heaven."

"The original silver-scaled fish species, as well as this keel boat, were both discovered there."

Chen Mu suddenly realized.

No wonder the Tang family stubbornly clung to the impoverished Tangshan Courtyard.

They weren't guarding Tangshan Temple, but Tianhe Cave.

"The Heavenly River Dharma Realm has two eyes, one of water and one of fire." Tang Zong continued, "The entrance to the fire eye is underground in Tangshan, and the entrance to the water eye is on the edge of Yizhou."

"Moreover, the Heavenly River Cave has been abandoned for a long time. There are many strange beasts inside, but no powerful monsters have ever been found."

“By using the Tianhe Cave as a transit point, we can not only shorten the total journey by half, but it will also be safer,” he said with a relaxed expression.

Is it really safer?
Chen Mu frowned and remained silent.

Monsters are fine, but I'm worried about those Yin Ghosts from Kangzhou causing trouble.

Back then, the Heavenly River Dharma Realm of Yunzhou was sealed off by the Locked Dragon Temple of Yunzhou, and he managed to escape with great difficulty.

just in case……

……

a few days later.

In a bubbling, dark red lava lake, a massive keel boat, resembling a black loach, floats on the lava surface.

Not far away, a huge, pitch-black sphere, as tall as a five or six-story building, floated quietly in mid-air.

An invisible repulsive force spread around it, and the lava lake was pressed down by the invisible force, forming a hemispherical depression.

Inside the dragon-bone boat, by the pool, Chen Mu stared at the black sphere appearing in the Luo Yan Mirror, quite hesitant.

“If the abbot is really worried, we can go to the Nihe Lower Academy,” Tang Zong suggested. “The closest entrance to the Tongtian River to Tangshan Academy is at Nihe Academy.”

That Niheyuan that produces one-yuan water essence?
That would be better than going to Tianhe Cave.

Chen Mu shook his head.

Niheyuan is located near the heart of Yizhou and was destroyed by demons more than half a year ago.

The first disciples that Tangshan Temple accepted who had fled were from Nihe Temple.

It's not very safe to enter Tongtian River from there.

"Are you sure there's nothing seriously wrong with this Heavenly River Cave?" Chen Mu frowned as he looked at Tang Zong.

"I did go in once three years ago, and there was definitely no danger then."

"Now..." Tang Zong was also a little unsure.

"How about I go in and scout it out first?" He hesitated for a moment, then gritted his teeth and suggested.

"Let me do it." Chen Mu waved his hand and summoned the giant spirit god, who was clad in crimson armor.

The Giant Spirit God is an avatar created by secret techniques. Even if it encounters an accident and collapses, it will only lose some magical power, making it perfect for scouting.

“The Giant Spirit God alone is not enough.” Chen Mu raised his hand and stuffed a Pulling Talisman Seed into the Giant Spirit God’s body.

Seeing the giant spirit slowly turn its head to survey its surroundings, as if it had come to life, a smile appeared on its face.

Since the Pulling Machine Method entered its seventh stage, not only has the number of talisman types increased to twelve, but it has also gained some memory and learning abilities.

With the help of the talisman, the giant spirit god is like having a brain. With some repeated training, it can master the ability to act independently.

He had previously used the talisman to control the giant spirit god, and together with the Zhu Yu magic sword, he could monitor the area around Tangshan Academy in real time.

Now, using the same old tricks, with slight modifications to the training, the Giant Spirit God has become a Qi Refiner version of a remote detector.

With a wave of his hand, Chen Mu sent the Giant Spirit God out of the Dragon Bone Ship, watching it silently disappear into the dark, lightless sphere. He waited patiently.

A quarter of an hour later, the giant spirit emerged from the black sphere, and a series of images immediately appeared in Chen Mu's mind.

"volcano?"

It seems that my accidental entry into the Heavenly River Dharma Realm of Yunzhou also happened within a volcano.

“Yes! It’s a volcano,” Tang Zongzhen exclaimed excitedly from the side.

"The two eyes of water and fire connect with the outside world, absorbing the primordial energy of water and fire with each breath, thus driving the operation of the cave."

"The fiery eye gathers fire energy, which is found in a volcano."

Chen Mu nodded slightly.

He replenished the giant spirit's magical power and waved his hand to send it back into the Heavenly River Cave.

……

three days later.

In front of the Golden Dragon Palace, Chen Mu stood by the pool, gazing intently at the Luoyan Mirror formed by white mist in mid-air.

After a while, the figure of the giant spirit god appeared in the clouds in mid-air.

Then, a flash of golden light appeared beside the two of them.

The vast amount of information carried within the Pulling Talisman also flooded into Chen Mu's mind.

"Director, how about I take some people from the Inspection Bureau in to investigate?" Tang Zong suggested quietly from the side.

That’s not necessary.

Chen Mu waved his hand.

Over the past two days, he has sent out the Giant Spirit God to explore the Heavenly River Cave multiple times.

Just as Tang Zong said, there were many strange beasts in Tianhe Cave, but no great demons were seen. Moreover, no trace of other people's activities was found, so it seemed that there was indeed no danger.

"That's more like it. I'm not some jinx, how could I possibly run into bad luck everywhere I go?" Chen Mu thought quite easily.

"Besides, I'm no longer the lowly Qi Refining cultivator who could only drift along with the tide."

"Even if something unexpected happens, with my current level of cultivation, I will definitely... I will definitely be able to rush to the gates of hell in the first instant!"

"Hmph! Don't even think about getting close to me!"

Chen Mu patted the railing, full of confidence.

"It's time to enter the Heavenly River Cave!"

He took a deep breath, and his magic flowed into the dragonbone boat from the soles of his feet.

The massive keelboat vibrated and slowly floated into the air.

It seemed to be swimming in water, slowly flying towards the black sphere. The moment of contact, it was sucked into it in a whoosh.

In just a few breaths, a volcanic interior landscape, radiating crimson light, appeared in the Luo Yan Mirror.

Chen Mu activated his Listening Ability and looked at the volcano, which was exactly the same as the information he had gathered before, and immediately smiled.

"Everything is going well, a good start."

Just as he was about to steer the dragonbone boat out of the volcano, a dragon's roar suddenly reached his ears.

Above the crater, countless stars suddenly appeared in broad daylight.

An invisible force suddenly descended, binding the dragonbone boat firmly.

The keelboat rocked violently, like a loach caught in a fishing net.

Amidst flashes of black and white light, the massive keelboat rapidly collapsed towards its center, like a bubble being popped, disappearing into thin air with a "poof."

The dark red magma continued to bubble and gurgle, and the volcano had an eerie calm, as if nothing had happened.
